Serena Williams and Ana Ivanovic pose with their trophies after the final match of the Western & Southern Open in August.

On the men’s side, top seed Novak Djokovic is the 6/5 favorite to win the U.S. Open after he won Wimbledon in July. Djokovic last won the tournament in 2011, when he beat Rafael Nadal in the final. Djokovic lost in the final in 2007, 2010, 2012, and 2013.

Andy Murray, who won the 2012 U.S. Open, is at 4/1 odds. Roger Federer, who won the U.S. Open five straight years from 2004 to 2008, is listed just ahead of him at 3/1 odds.
